I installed a 4 port 1gb Nic and I am trying to pass it through to a FreeBsd VM. However, when I create the VM I do not have any interfaces under "Other PCI Devices".

 

I went through spaceinvader Ones IOMMU tutorial and I cant get it to show in this vm.   Appreciate any help to get this working. 

 

This is my IOMMU group and I want to pass through "8086:10bc"

wrong info

@Armed Ferret I'm mot sure what method you used but normally I use this method & it works for me. go to your flash drive

Go to your flash drive, & add after append vfio-pci.ids=8086:10bc as in the picture, then reboot.

So as I said ... I watched Space Invader ones IOMMU passthrough video.  I did that already.  I also did the ACS over ride and altered the ACS override with the first bridge in the IOMMU group.  None of them work.  I can get the VM to launch but it does not boot all the way and there are no options in "Other PCI Devices".  I would appreciate some advice thats not in Space Invader Ones videos. 

@Armed Ferret is IOMMU enabled in your bios?

 

Its not an option in my bios.  I already checked.  However on unraid it shows enabled

How about other VM templates? The same situation? It`s a dumb advice but have you restarted your server? Also you can try to disable/enable VM manager in Unraid settings so it would re initialize all available pci devices.

 

The last suggestion that I have that you can add network ports manually in XML of VM like below, just check "slot" numbers are not already used in your VM by another devices, change them to any free if it would be required

 

   <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x08' slot='0x00' function='0x0'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x08' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
    </hostdev>

      <source>
        <address domain='0x0000' bus='0x09' slot='0x00' function='0x0'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x09' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
    </hostdev>

 

I got it working.  There is a plugin called vfio-pci cfg.

And it creates the config file required for the new way to do passthrough mentioned here
